Abstract

This paper investigates the effects of Ru/MCM-41 catalysts in the pyrolysis of waste tire using a semi-batch reactor. The pure silica support MCM-41 was synthesised via silatrane route. Prior to evaluating the activity of Ru/MCM-41 catalysts, the influences of MCM-41 and catalytic temperature were studied. The results indicated a strong impact of MCM-41 and catalytic temperature on the yield and nature of pyrolysis products. Oil yield first decreased then increased with catalytic temperature. However, the highest catalytic temperature produced the oil having a higher poly-aromatic content. Ru/MCM-41 catalyst produced much lighter oil and dramatically decreased the concentration of poly- and polar aromatics in the oil but also decreased the yield of oil. And the catalytic activity of Ru/MCM-41 was found to increase with Ru content in the tested range of ruthenium loading. The increase in catalytic activity was discussed in relation with catalyst characterisations.
